Seating and Safety Restraints
Reasons given...
"I have an airbag"
"I'd rather be thrown clear"
WARNING: Do not sit on top of a buckled safety belt or insert a
latchplate into the buckle to avoid the Belt-Minder chime. To
do so may adversely affect the performance of the vehicle's airbag
system.
Deactivating/activating the Belt-Minder feature (Driver only)
Note: If you are using MyKey , the Belt-Minder cannot be disabled.
Also, if the Belt-Minder has been previously disabled, it will be
re-enabled during the use of MyKey . Refer to MyKey in the Locks and
Security chapter.
The Belt-Minder feature can be deactivated/activated by performing the
following procedure:
Before following the procedure, make sure that the following conditions
are met:
• the parking brake is set
• the gearshift is in P (Park)
• the ignition switch is in the off position
• all vehicle doors are closed
• the driver's safety belt is unbuckled
• the parking lamps/headlamps are in the off position
WARNING: While the design allows you to deactivate your
Belt-Minder , this system is designed to improve your chances of
being safely belted and surviving an accident. We recommend you
leave the Belt-Minder system activated for yourself and others who
may use the vehicle. To reduce the risk of injury, do not
deactivate/activate the Belt-Minder feature while driving the vehicle.

Consider...
Airbags offer greater protection when
used with safety belts. Frontal airbags
are not designed to inflate in rear and
side crashes or rollovers.
Not a good idea. People who are
ejected are 40 times more likely
to DIE. Safety belts help prevent
ejection, WE CAN'T "PICK OUR
CRASH".
